1. Introduction

This is a collection of functions that allow extracting, transforming and exporting financial data.

These functions are special:

• They provide configuration
• They will be automatically turned into REST API endpoint
• They allow sharing data between commands

2. How to install?

GIT CLONE

Git clone the repository:

git clone git@github.com:OpenBB-finance/openbb-sdk-core.git

INSTALL

Install the package.

poetry install

3. How to add a plugin?

PROJECT

Build a Python package:

poetry new openbb-sdk-my_plugin

COMMAND

Add a router and a command.

# File my_plugin/plugin_router.py

from openbb_sdk_core.app.router import Router

router = Router(prefix="/my_name")

@router.command
def some_command(
    cc: CommandContext,
    query: StockQueryParams,
    provider: ProviderName,
) -> CommandOutput[Item]:
    pass

ENTRYPOINT

Add an entrypoint for the plugin inside your pyproject.toml file.

# File pyproject.toml
packages = [{include = "openbb_sdk_my_plugin"}]
...
[tool.poetry.plugins."openbb_plugins"]
plugin_name_space = "my_plugin.plugin_router:router"

INSTALL

Install your plugin.

poetry install

5. Usage

5.1. Update the settings

# FILE settings/user_settings.json
{
  "credentials": {
      "benzinga_api_key": null,
      "fmp_api_key": null,
      "polygon_api_key": null
  }
}

5.2. Define the CommandRunnerSession

from datetime import datetime
from openbb_sdk_core.app.command_runner import CommandRunner, CommandRunnerSession

app = CommandRunnerSession()

5.2.1. Use your OpenBB Hub account

# Create Hub manager
hm = HubManager()

# Connect with email, password or SDK token
hm.connect(email="your_email", password="your_password")  # pragma: allowlist secret

# Pull your settings
user_settings = hm.pull()

# Make the app aware
app = CommandRunnerSession(user_settings=user_settings)

# Change a credential
user_settings.credentials.polygon_api_key = "new_key"  # pragma: allowlist secret

# Send change back to Hub
hm.push(user_settings)

# Disconnect
hm.disconnect()

5.3. Define the Command parameters

from datetime import datetime
from openbb_provider.model.query.stock_query import StockQueryParams
from openbb_provider.provider.provider_registry import ProviderName

stock_query = StockQueryParams(
    symbol="TSLA",
    start_date=datetime.fromisoformat("2023-05-01"),
    end_date=datetime.fromisoformat("2023-05-04"),
)
provider = ProviderName.fmp

5.4. Run the command

command_output = app.run(
    "/openbb/stocks/fetch",
    query=stock_query,
    provider=provider,
).output

# Access the StockData
command_output.results

5.5 Run the static version (LEAST STABLE ON DEVELOP)

You also have the static version.

First update the cache:

from openbb_sdk_core.app.static.cache_builder import CacheBuilder

CacheBuilder.build()

Then run your command:

from openbb_sdk_core import openbb

stock_data = openbb.stocks.load(symbol="TSLA", start_date="2023-01-01", provider="fmp")
stock_data.dataframe()

5.5.1. App settings and system

from openbb_sdk_core.app.static import app
app.settings
app.settings.profile
app.settings.credentials
app.settings.preferences

app.system

5.5.2. Use your OpenBB Hub account

from openbb_sdk_core.app.static import app

# Login with email, password or SDK token
app.account.login(email="your_email", password="your_password", remember_me=True)  # pragma: allowlist secret

# Change a credential
app.account.settings.credentials.polygon_api_key = "new_key"  # pragma: allowlist secret

# Save account changes
app.account.save()

# Refresh account with latest changes
app.account.refresh()

# Logout
app.account.logout()

6. See routes

from openbb_sdk_core.app.router import CommandMap

command_map = CommandMap()
command_map.map

"{
'/ff/qa/load_random': <function ff_plugin.router.qa.qa_router.load_random(name: str) -> ff_plugin.router.qa.qa_router.CommandOutput[RandData]>,
'/ff/qa/calc_ret': <function ff_plugin.router.qa.qa_router.calc_ret(column: str, rand_data: ff_plugin.router.qa.qa_router.RandData) -> ff_plugin.router.qa.qa_router.CommandOutput[ReturnSeries]>,
'/ff/qa/garch': <function ff_plugin.router.qa.qa_router.garch(return_series: ff_plugin.router.qa.qa_router.ReturnSeries, p: int = 1, o: int = 0, q: int = 1, mean: str = 'constant', horizon: int = 100) -> ff_plugin.router.qa.qa_router.CommandOutput[GARCH]>,
'/ff/qa/summary': <function ff_plugin.router.qa.qa_router.summary(rand_data: ff_plugin.router.qa.qa_router.RandData) -> ff_plugin.router.qa.qa_router.CommandOutput[Dataset]>,
...
}

7. Using the REST API

Setup settings/user_settings.json:

# FILE settings/user_settings.json
{
  "credentials": {
      "benzinga_api_key": null,
      "fmp_api_key": null,
      "polygon_api_key": null
  }
}

Start the application:

uvicorn openbb_sdk_core.api.rest_api:app --reload

8. Static version (BEING REFACTORED)

Usage

from openbb_sdk_core.app.static.cache_builder import CacheBuilder

CacheBuilder.build()

from openbb_sdk_core import openbb

openbb.stocks.load(...)

9. Front-end typing

Here are libraries to get frontend typing.

openapi-typescript + openapi-fetch

• https://github.com/drwpow/openapi-typescript

openapi-generator

• https://fastapi.tiangolo.com/advanced/generate-clients/

10. Default User

There are 2 default users for testing purpose:

User "openbb"

• username : openbb
• password : openbb

User "finance"

• username : finance
• password : finance
